### 5/5 — Very Intuitive

*2025-08-18*

The program is very easy to learn. Also it is exactly what I was looking for. The finished product is great.

### 2/5 — Too basic

*2024-03-16*

Allows for single photo editing only. No HDR image bracket support. No option to sandwich multiple pictures together, e.g. +1, 0, -1 AB exposures taken with DJI drone, and no import of RAW / DNG files from files

### 1/5 — Moved to subscription-only

*2023-12-14*

Went from 5 stars to 1. Nobody wants software subscriptions. Especially when they paid for an app outright because they want to support developers that aren’t embracing this vampiric trend. We aren’t walking wallets.

**Developer response:** If you have paid for it, you don't need a subscription.

### 1/5 — BEWARE!!!   Not an HDR stitcher

*2023-02-13, version 3.0*

This is only an editor, it does not stitch multiple exposures to give true HDR. 
A rip off.

### 2/5 — Not a real HDR app

*2023-02-07, version 3.0*

Very good to ajust images and do effects but for HDR there is no real feature to take HDR photos et to ajust it!

### 1/5 — Impossible de Save

*2022-11-27*

Appli vraiment naze

### 5/5 — Very good HDR app!

*2022-11-11*

Simple to use and you can control the amount of HDR/sharpening.  Recommended!

### 5/5 — amazing 🔥👍🏼 app

*2022-09-15, version 3.0*

cool n simple

### 5/5 — Tolle App …

*2022-09-14*

sollte auf keinem iPhone/ iPad fehlen. Zahlreiche Bildbearbeitungsfunktionen sowie Filter u.v.a. lassen kaum Wünsche offen. Gern weiter so liebe Entwickler ;=)

### 5/5 — Très bien

*2022-02-17*

Très belle application. Merci à toute l’équipe.
